Joomla Coding Examples - Joomap

Joomap Component - Joomla SEO fix/patch to handle ChangeFreq, priority and lastmod for Joomap Version 2.0.5

Background
Joomap is a great component for creating a sitemap on your website.  It is also handy for generating a google sitemap which can be submitted to google.  The Sitemap generator is vital for google to map and find all of the files on your site correctly.  What Joomap does is allow google to find all of these links correctly.  I created this solution for my efforts in Search Engine Optimisation of Joomla.


The Problem
The problem with Joomap is that it does not have the changefrequency, priority and lastmod fields output in the sitemap XML file.  These modifications although not necessary and not included in the standard Joomap file do form a good improvement to the output of the filex XML.


The Solution
You need to locate the file "/components/com_joomap/joomap.google.php" and open it in a text editor.

Replace this code

                   $out .= "<url>\n";
                    $out .= " <loc>". $link ."</loc>\n";                        // http://complete-url
                    if( isset($node->modified) && $node->modified != FALSE && $node->modified != -1) {
                        $modified = date('Y-m-d\TH:i:s', $node->modified);        // ISO 8601 yyyy-mm-ddThh:mm:ss.sTZD
                        $modified .= sprintf("%+03d:00", $GLOBALS['mosConfig_offset']);    //TimeZoneDesignator
                        $out .= " <lastmod>". $modified ."</lastmod>\n";      
with the following code
                    $out .= "<url>\n";
                    $out .= "<loc>". $link ."</loc>\n";                        // http://complete-url
                    $timestamp = (isset($node->modified) && $node->modified != FALSE &&  $node->modified != -1) ? $node->modified : time();
                    $modified = gmdate('Y-m-d\TH:i:s\Z', $timestamp);        // ISO 8601 yyyy-mm-ddThh:mm:ss.sTZD
                    $out .= "<changefreq>daily</changefreq>";
                    $out .= "<priority>0.8</priority>";
                    $out .= "<lastmod>{$modified}</lastmod>\n";
